Chinese ebay seller.
Imagine, a Chinese using dodgy marketing to sell a blatant copy of a successful Chinese product.
Not sure if China has protection for their own companies against this sort of practice, but it's certainly not the case when they copy other countries successful products.
They are certainly masters of deconstruction and copying anything to a t.
Apart from the 1000mah battery (about 42% capacity of the Air) it seems to have RTH function, perhaps sensors etc, but they could be fake and inoperational.
It's certainly a toy, 80m, no mention if GPS or simple VPS for that stability they mention, AAA batts in the controller (and not included, lol).
I have to admit, when I first glanced at the ad, and saw the price, I thought simple scam.
Then I saw the non DJI brand name (Loumax).
Yes, they will sell a LOT of these to the unknowing.
And make a heap of $$$.
DJI should do something if it is within their legal capability there.
